Subject: Re: [Boost-users] I ran b2 with the -d+2 command and redirected the output to a file

I managed to build it with MSVC.  But none of the <cxxflags> arguments worked so I had to them all out of the configuration file.  

I think that this is partly because you are using Microsoft compiler options

https://docs.microsoft.com/en-us/cpp/build/reference/compiler-options?view=vs-2017

with Clang compiler

https://clang.llvm.org/docs/UsersManual.html#command-line-options

but also because the way of negating using b2/bjam is different, for example

-<toolset>msvc:<define>_DEBUG # Undefine DEBUG.

so to switch off permissive you should use

-<cxxflags>/permissive

and probably not

<cxxflags>/permissive-

But get it working before you try to enforce standards?

Sorry - I should have spotted this before.
